Revelation 4:1

Now it happened in the thirtieth year, on the fifth day of the fourth month, while I was by the river Chebar among the exiles, that the heavens were opened, and I saw visions of God.

I was in the Spirit on the Lord’s day, and I heard behind me a loud voice like a trumpet,

“Therefore write the things which you have seen, and the things which are, and the things which will take place after these things.

And they heard a loud voice from heaven saying to them, “Come up here.” Then they went up into heaven in the cloud, and their enemies watched them.

And the sanctuary of God which is in heaven was opened, and the ark of His covenant appeared in His sanctuary, and there were flashes of lightning and sounds and peals of thunder and an earthquake and a great hailstorm.

Then I saw heaven opened, and behold, a white horse, and He who sits on it is called Faithful and True, and in righteousness He judges and wages war.
